ATTACHMENT FOR SCREEN-DOORS-l 7 Application filed August 10, 1905. Serial No. 278,681.

To all whom it may concern.-

Be it known that we, ANDREW J. CARLsoN and HENRY S. JUVE, citizens of the United States, residing at Baltic, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Attachments for Screen-Doors, of-

which the following is a specification.

This invention embodies an attachment for doors, and is particularly designed inits preferred adaptation to be used in connection with screen-doors for holding the latter closed. As is well known, screen-doors often fail to closeentirely after they. have been opened, owing to the lack of proper'tension on the springs, at the hinges, or elsewhere, or

due to lack of sufficient movement to give the door impetus by which it will close. The invention provides a device which will automatically connect with the 'door as it closes to engage suitable means thereon and exert a normal positive force to pull the door closed entirely and hold it in such position.

For a full description of the invention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a broken perspective view show- .ing the invention applied to the frame of a door and a door mounted therein. Fig. 2 is a vertical section through the door, showing a side of the door-frame in elevation, the engaging member carried by the door having been engaged by the holding means upon the door-frame. Fig. 3 is a horizontal section, the parts shown in Fig. 2 being shown in top plan view in the arrangement illustrated.

Corresponding and like parts are referred to in the following description and indicated in all the views'of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the door, which may be a screen door or any similarly-mounted door, and the numeral 2 denotes the frame of the door. The door has secured thereto an engaging member in the form, preferably, of a loop 3, said loop being suitably attached at one end to the door, the other end being adapted to coact with means carried by the door-frame, as will be described hereinafter. The means carried by the door-frame, which cooperates with the member 3, is ada ted to automatically engage therewith as tlie door closes, and

Specification of Letters Patent.

The pivot 5 is prefera Patented Nov. 6, 1906.

said means comprises a lever 4, pivoted at its lower end to the door-frame, as shown at 5,

the upper end of said member 4 being bifurcated to form s aced fingers 6, between which the end of t e loop 3 is adapted to pass.

from a plate 6, suitably attached to the doorframe. A coiled spring 8 is secured at one end, as shown at 9, to the frame 2 of the door, the opposite end being attached to an eye 7 or lever 4. The tension of the spring 8 will hold the lever 4 inclined outwardly or toward the door 1, as shown in dotted lines in Fig. 2, or said spring 8 will hold the lever 4 in a position inclined in an opposite direction.

The position of the lever 4 when the door is open is such that the said lever is inclined outwardly toward the open door, resting on a stud 10, which projects outwardly from the door-frame-2 and which is the outer extremity of a screw-pin secured to said frame. When in the position above described and shown in dotted lines in Fig. 2, the s aced fingers 6 of the lever 4 are so arranged t at as the door closes the loop 3 will engage the more remote finger 6 as it enters the space between the fingers 6, and the impetus of the door will force the holding-lever 4 toward the position shown in full lines in Fig; 2 or inclined in an opposite direction, the spring 8 having been shifted and now tending to pull the lever 4 away from the door. The tension of the spring 8 is thus a positive force, coacting wit the lever 4 after it has been moved beyond its dead-center on the pivot 5 to pull said lever away from the door, and as the lever 4 is in engagement with the loop 3 the force acting onthe lever 4 will tend to pull the door closed and hold the same in this position. The force coacting with the lever 4 being only that of spring tension, however, it

. will be noted that when it is desired to open the door, all that is necessary to so do is to push or ap ly sufficient force thereto to overcome the orce exerted by the spring 8 and the holding lever 4 will be moved to the position shown in Fig. 2, the spring 8 then olding it against the stud 10, ready to be engaged by the member 3 as the door again closes.

It will be understood that the holding means comprised in the parts 4 and 8 and adjacent elements is adapted to be secured to any suitable support and will coact with a suitable member on the door to hold said door in the desired position. Further, in its ly a stud projected I QC preferred ada tation the lever 4 is not designed as a loci; member, especially when it is used in the manner illustrated and before described. It will of course be understood that the lever 4 automatically coacts with the engaging member 3, and this is an advanta eous feature of the invention.

t is to be understood that this invention eomprehends, broadly, the means provided to automatically connect with the door, and thereby efiect movement thereof into a predetermined osition, such position in the adaptation sl iown in the drawings being one in which the door is entirely closed.

Having thus described the invention, what is claimed as new is In a device of the class described, the combination of a door, a door-frame, door-closing means for the door comprising a lever pivoted at one end to said door-frame and aving its opposite end portion bifurcated to form spaced fingers, an eye projecting laterally from the lever at a point between its ends, a coiled spring connected at one end with the door-frame and having its opposite end connected with the eye projecting laterally from the lever, a loop member rigidly affixed to the door and adapted to enter the space between the fingers of the lever as said. door closes to initially move said' lever against the force of the spring, and a stud rojecting laterally from the door-frame to limit the movement of the lever whereby one arm thereof is held in engagement with the loop when the door is fully opened.

In testimony whereof we aflix our signatures in presence of two witnesses.
